7 To all whom it may concern:

Be it known that I, WILL H. VAN GUIL- nnn, of New Rochelle, county ofWVestchester, and State of New York, have invented a new and usefulImprovement in Molding- Machines, which improvement is fully set forthin the following specification and shown in the accompanying drawings.

The present invention relates to molding machines and more particularlyto that type designed for forming cement walls in situ, an object of theinvention being to provide an attachment for that type of moldingmachine disclosed in the application of Willis N. Britton filed July18th, 1910, Ser.

#570,585, such attachment being designed for forming pilasters upon thewalls. A further object of the invention is to provide a pilasterattachment which may be readily adjusted to form pilasters of differentsizes. To these and other ends, the'invention consists in certain partsand combinations of parts all of which will be hereinafter described,the novel features being pointed out in the appended claims.

In the drawings:

Fig. 6 is a top view of another pilaster attachment constructed inaccordance with this invention, this attachment being designed forforming a pilaster on a straight wall to permit the introduction offlues within the wall, and being shown as one of the connectionsbetweentwo molding machines of the type shown in the aforesaid Brittonapplication; v

Fig. 7 is a perspective view of the pilaster attachment shown in Fig; 6;and

Fig. 8 is a detail view of one of the ends of one of the walls of themachine shown in the aforesaid Britton application.

In the Britton application aforesaid, the molding machine embodies twoouter faceforming members or walls 1 and 2 connected together at theirends by connecting means 3 which also support two inner faceformingmembers or walls 4 and 5 for forming an air chamber, the walls 1, 2,land 5 beingmovable relatively to each other for the purpose of removingthe machine after the molding operation has been completed.

' The pilaster attachment, shown in Figs. 1

ner pilaster when supported by two of the aforesaid B'ritton machines orany other suitable meansand it preferably embodies four walls, two frontface-forming members and two lateral face-formin members, the frontface-forming members being arranged at angles to each other andpreferably pivoted at their meetingedges while the lateral face-formingmembers are arranged at the.

' to'5 inclusive, is capable of forming a corother edges of the frontface-forming memv bers and extend laterally with relation to saidmembers, being preferably rigid therewith, but adjustably connectedthereto so that the projection of the pilaster from the main wall may bevaried. Preferably, also the length of the front face-forming membersmay be variedfor the purpose of varying the-width of the pilaster.

The two front face-forming members may each embody a vertical framepiece 6 having lugs 7 extended therefrom and connected by a pintle 8with the lugs 7 of the other front faceforming member. From the ends 'ofthe upright frame piece 6, two laterallyextending frame pieces 9 areprovided, each having an'angle bar 10 secured to the outer facethereofand extending parallel therewith, the outer ends of the anglebars preferably being connected by a brace member 11 so that the parts6, 9, 10 and 11 form a frame section; -A 'sheetmetal plate 12 withlaterally-turned upper and lower edges is secured to. the fralne pieces9 and extends parallel to the frame section in spaced relation to theangle bars 10.

Between the angle bars 10 and the sheet 7' metal plate 12, another framesection forming part of the front face-forming member is adjustable andpreferablycomprises two parallel bars 13 having a sheet metal plate 14with laterally-turnededges secured thereto, bolts 15 bein passed throughopenings 16 in the angle bars 10 in order to engage the bars 13 forholding the two frame sections in different adjusted positions withrelation to each other for the purpose of increasing or decreasing thewidth of the face of the pilaster.

In this embodiment, a. lateral face-forming member is preferablyadjustable transversely of the plane of each of the front face-formingmembers and to this end preferably comprises an upright member 17 havinglateral extensions 18 at itsopposite ends to one face of which anglebars 19 are bolted at 20, these angle bars being adjustably connected tothe front face-forming member preferably by forming the bars 13 withlaterally-deflected ends 21 which by bolts22 are secured to the anglebars 19, the latter being provided with a number of openings 23 topermit the adjustment. The angle bars 19, by being secured to one faceof the extensions 18 permit the laterally deflected ends 21 to lie in aplane with the lateral extension 18- in order that the sheet metal plate2% having laterallyturned upper v and lower edges 25 and secured to theframe of the lateral face-forming member may overlap a lateral extension26 on the plate 1 1 so that no space will be provided when thelateralface-forming member is adjusted on the front face-forming member.

The aforesaid Britten molding machine has its outer face-forming members1 and 2 provided with eyes 27 at the opposite ends thereof and in orderto support the corner pilaster from two of these machines, one of thelateral face-forming members is provided with alined pintles 28 whichare adapted to be passed through the eyes 27 on one end of saidBrittonmolding machine. The other lateral face-forming membe isprovidedwith two alined projections 29 carried by a bolt or slide 30arranged for vertical movement on the upright frame piece 17, thusproviding a locking device for engagement within eyes 27 at one end ofan other. Britton molding machine.

For forming a molding chamber between the Britt-on molding machinesthere may also be combined with the corner pilaster, an angular wall 31which does not per 86 form the subject matter of the present invention,but which is detachably connected to the molding machines in a mannersimilar to the corner pilaster. An angular core piece 32 may besupported at its ends on the molding. machines in any suitable manner,this feature not forming the subject matter of the present invention.

In the use of the invention, the two molding machines are arranged atangles to each After the molding chamber be-' having. a lateralface-forming member rigidlybut adjustably secured to one end thereof,the parts being the same as one of front face-forming members and one ofthe lateral face-forming members of the attachment shown in Figs. 1 to5. This'pilaster also embodies a second lateralface-forming member whichis pivotally connected to the single front face-forming member. Thissecond lateral face-forming member embodies an upright frame piece 33having integral lugs 34 connected by pivot bolts 35 to the integral lugs7 on the frame piece 6. Adjustably arranged on the frame piece 33 is aframe section of U-shape having an upright piece35 formed withlateralextensions 37 at its opposite ends to which are bolted bars 38 which arepreferably provided with a seriesof openings 39 for the reception ofbolts 40, the latter connecting the bars 38 with the upright frame piece33.

The upright frame piece 36carries a locking member 30; which is providedwith alined projections 22 for engagement within the eyes 27 on one ofthe aforesaid Britten molding machines.

The embodiment of the invention illustrated in detail in Fig. 6 isadapted for forming a pilaster on an otherwise flat wall and. when soused may connect two molding machines ofthe type described in theaforesaid Britton application and illustrated par tially at m and 3 inFig. 6of the drawings of thisapplication, thepilaster. attachment beingillustrated by the connecting part shown at a. Combined with said,attachment is a connecting member '10 which is not claimed per se inthis application forms the subject matten ofanother application filed byWillisN. Britton on March 15th, 1913, Serial, #752,130; With thiscombination of parts, a wall may be molded about vertical 'flues, 25.After the, wall is molded, the attachments w and e are disconnected fromthe, molding machines w and y, permitting the latter also to be removed-In both embodimentsof the invention, a

ily connected to or detached from the ma chines and is extensible oradjustable to adapt it for forming pilasters of different depths andwidths. The attachment is so constructed that it may be moved from theformed or molded wall without injury to the corners of such wall.
